"Pokémon Detective Pikachu" will bring dozens of iconic Pokémon
to the big screen this week, rendering them in live action for
the very first time.

In both "Detective Pikachu" and the Pokémon games, Pokémon live
alongside humans in place of animals, making them a common sight
on city streets and in nature. The trailers for "Detective
Pikachu" are chock full of hidden Pokémon and fun nods to the
games that inspired the film.

The film will star Ryan Reynolds as the voice of the titular
character, with Justice Smith as his human partner. It's slated
to drop on May 10.

But with more than 800 Pokémon to keep track of, recognizing all
of them can be a chore. Luckily, we've done the extra work to
slow the trailers down and see just how many were brought to life
in the previewers. Through about half a dozen trailers, teasers,
and TV commercials so far, I've counted no fewer than 30 Pokémon.
Even more can be seen on ads and billboards in the film's
backgrounds.

Here are the Pokémon I spotted in both trailers, in the
order they appear.

These creatures crawling on the power lines at the start of the new trailer are actually a bug-type Pokémon called Joltik.

While Joltik is certainly big for a regular bug, it's actually one of the smallest Pokémon.

Ludicolo is a hilarious Pokémon that grows stronger when it hears happy music.

Known as "the carefree Pokémon," Ludicolo seems like a good choice as a bartending buddy.

The Ryme City Police have a few different Pokémon partners.

Growlithe, the puppy Pokémon also works with Officer Jenny in the Pokémon anime.

Arcanine is Growlithe's majestic-looking evolved form.

Lickitung is one of the original 151 Pokémon.

According to "Pokémon: Red and Blue," Lickitung's tongue is actually twice as long as its body.

Aipom is a monkey-like Pokémon with a three-fingered hand on its tail. They usually don't look so vicious!

"Pokémon Detective Pikachu"/Warner Bros. Pictures

In the games Aipom is almost always smiling, and the Pokémon is typically mischievous.

The Pokémon Company

Despite its gruff exterior, Snubbull, the fairy-type Pokémon, is a sweetheart.

Snubbull's pink, polka-dotted appearance belies its angry looks.

Machamp helps direct traffic, while a Snorlax naps nearby.

Pokemon Detective Pikachu

Unsurprisingly, Machamps are often seen working out with bodybuilders in the Pokémon games.

The Pokemon Company

Snorlax, on the other hand, is often found out asleep in public, blocking major roads in the process.

The Pokemon Company

Cubone, a small ground Pokémon, has a tragic backstory.

"Pokémon Detective Pikachu"/Warner Bros. Pictures

Early Pokémon games said that Cubone is actually wearing its mother's skull.

The Pokémon Company

Diplo, a popular DJ in the real world, makes a cameo appearance with two Loudreds.

"Pokémon Detective Pikachu"/Warner Bros. Pictures

As its name suggests, Loudred can create sounds capable of flipping trucks with its voice, and can use its ears as loudspeakers.

The Pokémon Company

The trailer shows off cage matches between a number of Pokémon.

"Pokémon Detective Pikachu"/Warner Bros. Pictures

Blastoise is the final evolution of Squirtle, one of the original three starter Pokémon. He's on the cover of "Pokémon Blue Version."

The Pokemon Company

Haunter is a ghost-type Pokémon from the first generation of Pokémon.

Flareon, a fire-type Pokémon, is shown in the trailer. Two legendary Pokémon, Dialga and Palkia, are shown as statutes in the background.

Flareon is one of eight evolutions of Eevee, one of the original Pokémon..

The Pokemon Company

Mewtwo was the villain of the first Pokémon movie, "Mewtwo Strikes Back."

Mewtwo has since made appearances in Nintendo's "Super Smash Bros." series, making use of his psychic powers.

The first trailer for "Pokémon Detective Pikachu" begins in Ryme City

"Pokémon Detective Pikachu"/Warner Bros. Pictures

The trailer's opening seconds feature more Pokémon than any other
scene as we're introduced to Ryme City, a location lifted
straight from the "Detective Pikachu" game. While several of the
flying Pokémon can't be clearly identified, I counted at least 8
monsters in this scene alone.

Flabébé is the floating flower Pokémon in the upper right hand corner of that shot.

Comfey spins through the sky as well.

Fearow stands out among the other bird Pokémon.

Emolga, the sky squirrel Pokémon, can be seen flying here, and again later in the Ryme City marketplace.

The Pokémon Company/Nintendo

Dodrio's heads stick out in the crowd.

The Pokémon Company/Nintendo

Charmander, one of the three starter Pokémon from the first game, passes by on the lower left, and later uses his tail to help light a fire in the marketplace.

Braviary can briefly be seen standing on the ground on the right-hand side.

Bouffalant trots through the bottom of the frame.

Later, we see Psyduck and Lucy (Kathryn Newton) on the street — with more guest stars in the background.

"Pokémon Detective Pikachu"/Warner Bros. Pictures

Psyduck was a familiar face in the early seasons of the Pokémon TV show.

Pikachu has always been the mascot of Pokémon, but Detective Pikachu is a new character introduced in 2016. He debuted in a Nintendo 3DS game of the same name.

The Pokémon Company/Nintendo

The trailer also shows us the Ryme City Marketplace.

"Pokémon Detective Pikachu"/Warner Bros. Pictures

In addition to Emolga and Dodrio popping up in the background
with Pikachu, there's one more visable Pokémon in the crowd.

Audino, the hearing Pokémon, can be seen standing on the right side of the market.

The Pokémon Company/Nintendo

The shot also shows us some Bulbasaur wading through a stream.

"Pokémon Detective Pikachu"/Warner Bros. Pictures

Bulbasaur is the very first Pokémon in the Pokedex.

Morelull glow as they float through the air.

The Pokémon Company/Nintendo

We get our first glimpse at this adorably angry Jigglypuff, apparently in residence at a cafe.

"Pokémon Detective Pikachu"/Warner Bros. Pictures

Jigglypuff singing folks to sleep is a gag that's almost as old as the franchise.

The Pokémon Company/Nintendo

Things take a turn for the scary when we see Charizard in a cage.

"Pokémon Detective Pikachu"/Warner Bros. Pictures

Charizard is one of the series' most iconic Pokémon, appearing on the box and cartridge of "Pokémon Red."

The Pokémon Company/Nintendo

We also see a pack of Greninja.

"Pokémon Detective Pikachu"/Warner Bros. Pictures

The trailer shows a group of Greninja chasing Pikachu and Tim through multiple scenes. The ninja frogs first debuted in "Pokémon X and Y," in 2013. Fun fact: Greninja's "scarf" is actually his tongue.

The Pokémon Company/Nintendo

We go back to the cage with the missing Pokémon.

"Pokémon Detective Pikachu"/Warner Bros. Pictures

Three Pokémon inside the cage with Tim and Pikachu can easily be missed in this dark scene, including Squirtle and Panchan, who are both shown on missing-persons (or missing-Pokémon) posters earlier in the trailer. Panchan is standing at the bottom of the cage as the camera fades in.

The Pokémon Company/Nintendo

Squirtle, the last of the three starter Pokémon from the original games, can be seen behind bars on the right side of the screen.

The Pokémon Company/Nintendo

Rufflet appears just underneath Pikachu's tail.

The Pokémon Company/Nintendo

A memorable scene shows the interrogation of Mr. Mime.

"Pokémon Detective Pikachu"/Warner Bros. Pictures

Mr. Mime is one of the original 151 Pokémon — and certainly one of the weirdest.

The Pokémon Company/Nintendo

The "Detective Pikachu" trailer is stuffed full of Pokémon with
just two minutes of runtime, and much of what we see in the
background of Ryme City suggests that we'll be seeing many, many
more when the film releases next year. With more than 800
different species of Pokémon to chose from, Warner Bros. has
plenty of options.
